4. 13. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Máté Károly Tóth; [2023]
   Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

5. 14. Load-velocity profiles as a predictor of performance level in swimming : What differentiates international elite swimmers from national elite – force capacity or efficiency?

   Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för fysiologi, nutrition och biomekanik

   Författare :Maria Vitazka; [2023]
   Nyckelord :Load-Velocity; Force-Velocity; Force Capacity; Swimming; Biomechanics; Performance indicators; International elite; swimming performance; 1080 Sprint; 1080 Motion; Semi-tethered force measurements; tethered force measurements; maximum velocity; load; force; swimming efficiency;

   Sammanfattning : Aim  The purposes of this study were to investigate if the load-velocity (L-V) profile parameters – force capacity and efficiency - differ between swimmers of different performance level, and to investigate if efficiency is the key performance indicator between international elite and national elite level swimmers.  Method  Fifty-four swimmers (27 female and 27 male) of either regional level, national elite or international elite level, participated in this study.
